Microcytic anemia is the condition wherein red blood cells are smaller than normal, and it is primarily caused by iron deficiency anemia and thalassemia, according to Dr. Siamak T. Nabili writing for eMedicineHealth. Iron deficiency anemia occurs due to limited or inadequate iron intake.
Red blood cells carry oxygen and nutrients to the tissues in the body and take away carbon dioxide. They are also called erythrocytes. They get their red color from a pigment called hemoglobin, and it is the hemoglobin that actually carries the oxygen and carbon dioxide.
Large red blood cells, called macrocytosis, are not a cancer symptom but may signal a problem that needs to be examined medically, explains Mayo Clinic. Macrocytosis is not a disease and does not produce symptoms or signs. Vitamin B-12 or folate deficiencies, liver disease, hypothyroidism and alcoho
According to Springfield Technical Community College, the primary role red blood cells play in the body is to transport oxygen from the lungs to the various body tissues. To carry out this task, the cells are filled with a substance called hemoglobin. Hemoglobin is so important to red blood cells th
A normal red blood cell lives for about 120 days. It takes about two days for the body to manufacture each red blood cell, and about two million are turned out every second. Production of new red blood cells occurs in the bone marrow.
Humans have red blood because it contains iron. Another way of explaining why humans have red blood is that the color is due to hemoglobin, which is the protein associated with iron that makes blood red.
Two adaptations that have been made by the red blood cell are the lack of a nucleus and organelles, or small, specialized bodies in the cell. This allows for more room in the blood cell for hemoglobin.
According to the Mayo Clinic, enlarged red blood cells, or macrocytosis, is a non-specific medical condition that has a number of different causes.
